Summary Thirteen clones of Populus tremuloides (Michx.) from central Alberta, Canada, were sampled to determine variation patterns within and among clones for benzene-alcoholwater extractives. Significant differences among clones were present; however, the broadsense heritability for extractive content was low (0.13). Extractive content was highest near the pith and decreased outward. Genetic and phenotypic correlations between rate of growth (ring widths) and extractive content indicated that faster growing clones or trees tend to exhibit less benzene-alcohol-water extractives.The authors would like to thank the Forest Development Research Trust of the Alberta Department of Energy and Natural Resources, and Natural Science and Engineering Research Council of Canada (NSERC A 1281, NSERC-SPF 00291) for financial support |
